Abstract: The standard grey and color test chart has six different color pat-ches and seven grey patches of different luminous reflectance. The sixcolors are red, green and blue, cyan, magenta and yellow. The percent-ages of reflectance of the seven grey patches are 91.8, 44.6, 23.4, 12.8, 6.0,3.8, and 18.0. The grey and color reflection chart is to be used as stan-dards in quantitative analysis of color reproduction in various photog-raphic techniques.
